C-13-Q087mediumsingle_mcq

After $10\%$ deduction for provident fund, the first three terms of Palash's net salary series are —

a $108000 + 112500 + 117000$
b $120000 + 125000 + 130000$
c $108000 + 113000 + 118000$
d $108000 + 112500 + 116500$

ব্যাখ্যা

A $10\%$ PF deduction leaves $90\%$ of each gross figure. So $0.9\times120000=108000$ , $0.9\times125000=112500$ , and $0.9\times130000=117000$ .
